For any newbie to start in developing, I think you needs a good android programming book.
You can find a lot at android programming books at book store.
I recommended the book "Beginning Android Application Development" by Wiley Publishing, and "The Busy Coder's Guide to Advanced Android Development".
When learning programming, the "Android Developer" website by google will help you a lot..
For me, I start android programming 1 years ago, now I have just complete developed 9 apps and already published in market a few days ago...
